Application'filed November 28, 1908. Serial No. 464,824.

To all whom it may concern:

Be it known that I, AMBROSE CoNKLn, a citizen of the United States,residing at Luray, in the county of Clark and State of Missouri, haveinvented certain new and useful Improvements in Road-Machines, of whichthe following is a specification.

My invention relates to an improvement in road machines, the objectbeing to provide a machine which will have the combined function of adrag scraper, and a ditching machine, it being provided with adjustablemeans for guiding it with respect to the ditch, so that it will maintainthe same rela tive position with respect to the ditch as it is usedalong the edge of the road.

Another object is to provide means for adjusting the depth of cut at anyand all parts of the machine, the adjustment all being within reach ofthe driver who is seated upon the machine, and a further object is toprovide means for changing the application of draft in accordance withthe position and work of the machine on the road.

With these several objects in view, my present invention consists incertain novel features of construction and combinations of parts whichwill be hereinafter described and pointed out in the claims.

In the accompanying drawings :Figure l is a plan view showing the moldboard extending in one direction, and one application of the draftmechanism to the ditch runner folded, Fig. 2 is a plan view showing aform in which the mold board extends in the opposite direction, and theditch runner extended for operation, and the draft mechanism ready touse with the machine when forming a ditch for operating at the side ofthe road, Fig. 3 is a side elevation, and, Fig. 4: is a section.

A rigid V-shaped frame A constitutes the main portion of the machine,member 2 of which corresponds to the land side, and member 3 to the moldboard, of a plow. These members 2 and 3 are rigidly secured together bybolts or other means at the forward end, and held apart at the rear bymeans of a brace 4, and at an intermediate point by the brace 4. Thesemembers 2 and 3 are the same as in my Patent No. 882,053, granted March17, 1908, upon which machine the present is an improvement, and as inthat machine, member 2 or land side 1 is provided with a straight metalrunner 5 or guide bar, and the member 3, or mold board, is provided witha curved cutting blade 5 My present invention is provided with threewheels 6, 7, and 8, one for each of the three corners. The operatingmechanisms for these three wheels differ slightly. These wheels arevoperated to regulate the depth of the cutting blades of the members 2and 3. Wheel 6 is journaled at the rear end of abell crank lever 10which latter turns 011 a fulcrum 11, and a. rod 12 extends from theupper end of this bell crank lever 10 to a segment 13, mounted on themember 2. A worm 14 on the worm shaft 15, engages the teeth of thissegment, and a wheel 16 on the upper end of shaft 15 is provided as aconvenient means for turning the worm shaft and worm in the adjustmentof the wheel 6. hen the wheel 16 is turned to the right, for instance,it pulls the rod 12 rearward, forcing the wheel 6 downward, and raisesthe forward end of the machine, thus lessening the depth of out at thatpoint. Wheel 7, preferably V-shaped, is journaled at the rear end of abell crank lever 17 which is fulcrumed on the stud 18, and a rod 19extends from the upper end of this bell crank lever 17 to an arm 20 onthe shaft 21 of the hand lever 22. This hand lever has the usual latchmechanism 23 which operates in connection with a segment 24 forfastening it in position. Hand lever 22 like wheel 16 is located inclose proximity to the drivers seat 25, within reach of the operator ofthe machine. By releasing the latch 23, the lever 22 may be operated forraising or lowering the wheel 7 which will either raise or lower the endof the bar or land side 2 for penetrating very hard ground. When it isdesired to have the end of the bar penetrate deeply, the lever is thrownso that the wheel is lowered, causing the machine to be raised, so thatthe bottom of the memher 2 is at an angle to the surface of the ground,which permits of the machine penetrating deeply into the soil.

lVheel 8 is provided with a shank 26 which is guided in its upward anddownward movements between the concave pulleys 27, 27. A lever 28,fulcrumed at 29, engages the lower end of the shank, and this wheel isshown in Fig. 3, and a hand lever 30, similar to lever 22, having asimilar latch 31, engaging a segment 32, is L-shaped at its lower end33, and connected by the rod 34:, to this lever 28, so that by swingingthe lever in one direction, it raises the'wheel 8; in the oppositedirection it lowers it. This lever also is Within easy. reach of thedriver, as shown in Fig. 2, so that he has all points of the machineunder control and may regulate the depth of out.

, The ditch runner 35 is pivotally mounted at 36, 36, on the land sidemember of the machlne. lVhen in use, this runner is spread out, as shownin Fig. 2, and its outer end is adapted to engage and travel'along theedge as a guide to hold the machine to its work on the-slope of the roadadjacent thereto, thus making the machine'not only a successful dragscraper upon a more or less'fiat and level stretch, but also aneflicient ditching machine along the sloping sides of'the road. When notin use, this ditching device. may be folded over the center of themachine as shown in Fig. 1, where it is out of the way.

The draft attachment is quite similar to that disclosed in'my patentabove referred to, except that in the ditching operation, the

rods 40, 41, and swingle-tree 42 are removed from section .3, andtherdouble-tree hook 43 7 may be hooked into the chain 44 at the pointdesired, so as to bring the draft nearer the point of the machine asshown in Fig. 2.

In this way, I have provided a machine which is equally. useful at anypoint on the surface of the road,- whether at the sides, and in theformation of the ditches, or at Copies of this patent may be obtainedfor resorted to in the form and arrangement of the several partsdescribed without departlng from the spirit and scope of my inven-'tion, and hence I donot wish to limit myself to the exact constructionherein set forth, but i Having fully described my invention, what Iclaimas new and desire to secure by Letters Patent, is

1. In a road machine, the combination with a land-side and mold-boardportion converging to a point, of a ditch-runner hinged to the land sidein a manner to swing laterally or vertically above the latter.

2. In a road machine, the combination with a land-side and mold-boardportion converging to a point, of a ditch runner, hinged to the machineat points longitudinal thereof and in a manner to swing laterally togage the position of the machine with respect to the furrow or ditchpreviously cut.

In testimony whereof I afiix my signature in presence of two witnesses.
